Yup, and it only cost $325 million for the project.

A mere drop in the bucket.

Consider that the US spends 1753 billion dollars per year, or 4.8 billion dollars PER DAY, on welfare...

https://www.usgovernmentspending.com/us_welfare_spending_40.html

.... so this project cost less than 2 hours of the welfare budget.

I would call that a real bargain!

Indirect investment into the economy!
Welfare recipients spends the money on rents, food etc...
Stores are relying on this money!
Also, saves the country from a revolution from the poor, burning up the city.
Soon France starts the Universal income.
Actually, paying people not to work!
Have you heard of subsidizing farmers not to grow food etc...?
Same thing!

In another newsgroup, I saw a reference to how, some time ago, an
astrologer sued the U.S. government to stop some other asteroid
deflection effort on the grounds that it would interfere in the accuracy
of astrological prediction.

This led me to realize something about the DART mission.

To view an asteroid as not something that travels eternally on an
assigned path in the sky, but as a massive body, moving under the
influence of gravitation and momentum and inertia, and hence
subject to an alteration of its motion due to crashing something
into it... requires adherence to the Newtonian view of the heavenly
clockwork.

Ah, I've found the detail. It was the Russian astrologer Marina Bai who
sued, in response to the Deep Impact mission to the comet Tempel 1.

In the final moments before impact, mission control sees that the target has portholes, antennas and strange Klingon-like lettering on its exterior.

The impact has given the asteroid a really good shake up and it has now
developed a long cometary tail as seen by SOAR in Chile in this image.

I wonder if the two apparent tails front and back are recent trajectory
and away from the sun like they would be for a normal comet or whether
one of them is radial to the impact site ?

I still recall watching Hale-Bopp's nucleus spinning and emitting a
spiral bright outflow taken by Terry Platt of Starlight Xpress.

I can't find that one but this is an example (though not as good)

Ah got it! But the timing is a bit screwy in the MPEG so it plays way
too fast - blink and you will miss it. It was a tour de force in its
day. It could do with slowing down 5x.
